A process that creates deep gorges on the land surface is?
Awọn alaye Idahun
The process that creates deep gorges on the land surface is gully erosion. Gully erosion occurs when water flows rapidly over an area of land, creating channels or gullies that can deepen over time. This often happens in areas where the soil is exposed and not protected by vegetation or where the slope of the land is steep, allowing water to gain momentum as it flows downhill. Gully erosion can have significant impacts on the environment, including the loss of fertile soil and damage to infrastructure such as roads and buildings. In summary, gully erosion is a process of land degradation that creates deep channels or gullies on the land surface due to the rapid flow of water over exposed soil in areas with steep slopes.

Commercial agriculture in the tropics concentrates on the production of?
Awọn alaye Idahun
Commercial agriculture in the tropics concentrates on the production of rice. This is because rice is one of the few staple crops that can be grown in the hot and humid conditions found in tropical regions. Rice requires a lot of water and can thrive in flooded fields, making it an ideal crop for areas with heavy rainfall or access to irrigation. In addition, rice is a high-yielding crop that can support large populations, making it an important food source in many tropical countries. Other crops, such as wheat and millet, require drier conditions and cooler temperatures to grow, and are therefore not well-suited to tropical agriculture. Tea is also an important crop in some tropical countries, but it is typically grown in cooler upland areas rather than the lowland areas where rice is cultivated. In summary, commercial agriculture in the tropics concentrates on the production of rice because it is a high-yielding crop that can be grown in hot and humid conditions, and is an important food source for many people in tropical regions.

Awọn alaye Idahun
One distinguishing characteristic of ferruginous soils is the occurrence of iron concretions in the B horizon. Ferruginous soils are soils that are rich in iron oxides and have a distinctive reddish-brown color. They are found in areas with a tropical or subtropical climate and are usually formed from the weathering of iron-rich rocks. The B horizon is the layer of soil below the A horizon, and it is characterized by the accumulation of minerals and organic matter that have been transported down from the surface. In ferruginous soils, iron oxides accumulate in the B horizon, forming iron concretions or nodules. These concretions are hard, dense, and often spherical or elongated in shape. They can range in size from a few millimeters to several centimeters in diameter. The occurrence of these iron concretions is a distinguishing characteristic of ferruginous soils and is used to identify them in the field.

Sedimentary rocks are distinguished from other rocks by their?
Awọn alaye Idahun
Sedimentary rocks are distinguished from other rocks by their strata. Sedimentary rocks are formed from the accumulation and cementation of sediment, such as sand, mud, and pebbles, over time. These sediments are deposited in layers, or strata, which build up and eventually become rock. The layers in sedimentary rocks are usually visible to the naked eye and can often be distinguished by differences in color, texture, and composition. This layering is a distinctive feature of sedimentary rocks and sets them apart from other types of rocks, such as igneous or metamorphic rocks, which do not typically exhibit such a layered structure. Joints, or cracks, can occur in all types of rocks, including sedimentary rocks, but they are not a defining characteristic of sedimentary rocks. Similarly, while sedimentary rocks can be compact and hard, this is not unique to this type of rock. Finally, sedimentary rocks are not typically crystalline in nature, unlike igneous and metamorphic rocks, which are formed through processes involving intense heat and pressure.

Awọn alaye Idahun
The speed of wind is usually measured using an anemometer. An anemometer is a device that is used to measure the speed of wind. It works by rotating in response to the wind, and the speed of rotation is proportional to the speed of the wind. The most common type of anemometer used today is the cup anemometer, which has three or four cups mounted on horizontal arms that spin when exposed to the wind. The number of rotations per minute is measured, and this is used to calculate the wind speed. Other types of anemometers include the vane anemometer, which uses a propeller and wind vane to measure both wind speed and direction, and the hot-wire anemometer, which uses a heated wire to measure the rate of cooling caused by the wind. However, the most commonly used anemometer is the cup anemometer. Therefore, to measure the speed of wind, an anemometer is used.

One direct adverse environmental effect of deforestation is?
Awọn alaye Idahun
One direct adverse environmental effect of deforestation is escalated soil erosion. Deforestation refers to the process of clearing forests or trees from a land area, typically for the purpose of converting it to non-forest use, such as agricultural or urban development. When forests are cut down, the vegetation and trees that previously held the soil in place are removed, leaving the soil exposed to the elements. This makes the soil more susceptible to erosion, especially during periods of heavy rainfall or strong winds. Soil erosion can have a number of negative impacts on the environment. It can lead to the loss of topsoil, which is rich in nutrients and supports plant growth. It can also cause increased sedimentation in waterways, which can harm aquatic ecosystems by reducing water quality and disrupting the food chain. Additionally, soil erosion can contribute to landslides and other natural disasters, further damaging the environment and potentially endangering human populations. Overall, deforestation can have significant negative impacts on the environment, including escalated soil erosion, which can in turn have a range of additional adverse effects.

The effect of ocean currents along the coasts they wash are experienced?
Awọn alaye Idahun
The effect of ocean currents along the coasts they wash is experienced when prevailing winds are onshore. Ocean currents can have a significant impact on the coastal environment, affecting factors such as water temperature, salinity, and nutrient content. When prevailing winds are onshore, they drive surface waters towards the shore, leading to an accumulation of water along the coast. This can cause an increase in water level, known as a coastal upwelling, which can have several effects. For example, the upwelling can bring cold, nutrient-rich water to the surface, which can stimulate the growth of marine organisms such as phytoplankton. This can in turn attract fish and other marine life, making the area an important fishing ground. On the other hand, coastal upwelling can also lead to the cooling of water temperatures, which can impact marine ecosystems and weather patterns in the region. In summary, the effect of ocean currents along the coasts they wash is experienced when prevailing winds are onshore, and this can have significant impacts on the coastal environment and local communities.

Rocks often develop cracks when they are exposed to?
Awọn alaye Idahun
Rocks often develop cracks when they are exposed to compression and tension. Compression occurs when rocks are pushed together, while tension occurs when rocks are pulled apart. Both of these forces can cause rocks to develop cracks, which can vary in size and orientation depending on the type of force applied and the properties of the rock. Additionally, joints and faults can also contribute to the development of cracks in rocks. Joints are natural fractures that occur in rocks, often as a result of tectonic movements or other stresses. Faults are more significant fractures in the Earth's crust that result from the movement of tectonic plates. Both joints and faults can create pathways for water and other materials to penetrate rocks, further contributing to their weathering and erosion. Overall, it is the combination of compression and tension, as well as other geological processes such as jointing and faulting, that can cause rocks to develop cracks over time.

Shifting cultivation in agriculture involves?
Awọn alaye Idahun
Shifting cultivation in agriculture involves cultivating alternative plots to allow natural regeneration. Shifting cultivation, also known as slash-and-burn agriculture, is a traditional farming practice in which farmers clear a plot of land and burn the vegetation to release nutrients into the soil. They then cultivate crops on that plot for a few years until the soil loses its fertility, and then move on to another plot of land, allowing the first plot to naturally regenerate over several years. This method of farming is often used in areas where the soil is poor and does not support intensive or continuous cultivation. Shifting cultivation is typically used for subsistence farming, where farmers grow crops mainly to feed themselves and their families. It is also used for cultivating cash crops for local markets, rather than for export. Shifting cultivation is often associated with indigenous and traditional communities, who rely on this method for their livelihoods and cultural practices.

Awọn alaye Idahun
Access to water and kinship ties can lead to nucleated settlements. Nucleated settlements are communities where houses are clustered together in a small area. These settlements are often located near a source of water such as a river or a well. When a community has access to water, they can irrigate their fields and provide themselves with enough water for drinking and cooking. Moreover, kinship ties can also lead to the formation of nucleated settlements. People who are related by blood or marriage often choose to live close to each other to support and protect each other. This results in the clustering of houses in a small area. Therefore, when a community has access to water and strong kinship ties, they are more likely to form nucleated settlements. Other settlement types, such as ribbon, loose-knit, or dispersed settlements, may form under different circumstances.
